so the magnetic field pushes the particle instead of pull? then how is there circular motion?

With learning must come humility and acceptance as well, i am sorry to have lied about the examiner report, after some proper thinking i have concluded that the right answer is B, using my earlier reasoning for the centripetal force and magnetic force, the magnetic field indeed goes into the...

Thank you for everyone's time and support, i wish to close this thread, since this question is no longer needed of my interest anymore

here's the deal, if you can prove the answer is B using high school physics then I will send the examiners report

I love how we members on physics forum love to debate about completely useless things even though its wrong 😂😁😂

Hey thanks for your opposition but upon checking examiner reports I have verified that the answer is truly A. It really is hard to try prove something that is the opposite of correct!

i think this might be some what of a good reasoning though it depends on perspective. The direction of the magnetic field around the positive particle is indeed into the page but that doesn't automatically mean the direction of magnetic field causing the motion is into the page. To verify that...

i sort of get all of this but there is no base level reasoning for why the mark scheme is right (if its right in the first place). We are clearly not meant to know anything above Flemings left hand rule, right hand grip rule, centripetal forces (for circular motion) and magnetic field induction.

yes i did consider the field around the loop instead of the actual direction of the magnetic field, but whats the difference?

but Chatgpt said its meant to be A and its a mark scheme error with a bit of reasonable justification. Please refer to this link: https://chatgpt.com/share/6845a79a-6734-800b-9a5b-8f926625ce91 or i can send individual screen shots if you don't want to access the link

i thought it was flemings left hand rule. How do we relate this with the question, is there not a strait up solid answer

is there a basic high school level explanation because im pretty sure our syllabus didnt expect students to know Lorentz force law

inward towards the center (centripetal force)?

Good day, Im a high school student currently working on my exams, I have came across a past paper question in which my answer contradicts the mark. To answer the question i used the right hand thumb rule since the direction of positive charge movement is similar to conventional current and...

so if drag force doesn't increase at a constant rate then the acceleration time graph wont be linear. So is the image provided right about the acceleration time graph for terminal velocity.
